Preprocessor behavior

[Munagala Ramanath]

Hi,

Using the macro:
#define T( X ) L ## X
to create a wide string fails with the predefined __FILE__ symbol
(i.e. T(__FILE__)) with gcc-2.95.2 on Sparc/Solaris7 because it
apparently catenates the body to get L__FILE__ before rescanning.

MSVC yields the expected L"<filename>".

Is this a bug in gcc or is it required by the standard ? Does anybody
know any way to generate wide string literals out of __FILE__ ? Thanks.
